Pros & Cons
Pros
Comes with a variety of adapters to fit any engine that uses a carburetor. Cleaned the throttle plate/body and immediately saw an improvement per the scanner of the throttle position. Works very well to show the level of vacuum being pulled by the pum... Read More
The only shortcoming is the connectors, t's, etc. If you place a screen protector on the cover that should eliminate the only downfall of the product. No leaks, and ready to go with minimal setup.

Cons
The gauge doesn't zero out, it doesn't pick up a good vacuum read, it has no adjustment. The rubber sealing washer in the end of the hose connector is not fuel resistant and mine dried out and cracked in about 3 months of use.

Ive used the fuel pressure tester quite a bit and it works very well but it doesnt come with many fittings for modern cars so i had to order them separately

I initially thought it was the fuel pump but once i connected the gauge i could see that it had good fuel pressure which did not drop off when the pump stopped running

I then tried to start it with the fuel rail at pressure but the relay out so that the pump did not run
